The COWB3 Boiler: Efficient Performance for Years You never know just how harsh the winter will be, so why risk your family’s warmth? Be prepared for the worst – and cozy all winter – with a Lennox® COWB3 boiler. This standard-efficiency heating system uses a Beckett® oil burner, the product that set the standard for fuel-efficient heating. A domestic hot water coil takes your energy efficiency further by providing hot water at virtually no additional cost. Winter temperatures are one thing, but it’s the wind that takes winter cold to the next level. That’s on reason why we love the COWB3 system’s sealed-combustion construction. Not only is your heating quiet, it’s also draft-free. What makes this product even better is its effortless integration with traditional radiator systems. When you buy a COWB3 boiler through your Strand Brothers Service Experts Heating & Air Conditioning in Austin, you’ll get reliability, durability and expert furnace installation service. Ready to see what a new heating system can do for you? The COWB3 boiler is available in three models so you can choose the best one for your home.
